Properties

6 of its own, and 14 it inherits. Each says what kind of value it takes.

Its own6
PropertyValueWhat it means
authorValue: Organization or Person

The author of this content or rating. Please note that author is special in that HTML 5 provides a special mechanism for indicating authorship via the rel tag. That is equivalent to this and may be used interchangeably.

bestRatingValue: Number or Text

The highest value allowed in this rating system.

ratingExplanationValue: Text

A short explanation (e.g. one to two sentences) providing background context and other information that led to the conclusion expressed in the rating. This is particularly applicable to ratings associated with "fact check" markup using ClaimReview.

ratingValueValue: Number or Text

The rating for the content.

Usage guidelines:

  • Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.
  • Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.
reviewAspectValue: StructuredValue or Text

This Review or Rating is relevant to this part or facet of the itemReviewed.

worstRatingValue: Number or Text

The lowest value allowed in this rating system.

PropertyValueWhat it means
additionalTypeValue: Text or URL

An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.

alternateNameValue: Text

An alias for the item.

descriptionValue: Text or TextObject

A description of the item.

digital.org.aiValue: Number

Digital maturity score from 0.0 (fully analog/manual) to 1.0 (fully digital/autonomous). Indicates the degree to which an entity operates digitally.

disambiguatingDescriptionValue: Text

A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.

identifierValue: PropertyValue, Text or URL

The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.

imageValue: ImageObject or URL

An image of the item. This can be a URL or a fully described ImageObject.

mainEntityOfPageValue: CreativeWork or URL

Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.

nameValue: Text

The name of the item.

ownerValue: Organization or Person

A person or organization who owns this Thing.

potentialActionValue: Action

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.

subjectOfValue: CreativeWork or Event

A CreativeWork or Event about this Thing.

urlValue: URL
